8. An app connects to one app container A container connects to multiple data sources data sources data sources data sources

9. different containers fulfill the contract in different ways. in different ways. in different ways.

10. The app does not contact data sources directly. That’s the container’s job. That’s the container’s job. That’s the container’s job.
